View Mosaic Dataset Properties

After selecting one or multiple mosaic datasets in the Workspace Manager, right-click and choose the Properties option from the context menu. This will open the dataset properties panel on the right side of the map window. In the properties panel, you can view or modify the basic information, coordinate system details, and no-value information of the mosaic dataset.

Dataset

Clicking the Dataset option in the properties panel will display the basic information of the mosaic dataset, its extent details, and a detailed dataset description.

The basic information includes the dataset name, type, table name, and dataset encoding method.

Dataset extent:

  • The upper and lower values represent the two boundaries along the Y-axis (Y=).
  • The left and right values represent the two boundaries along the X-axis (X=).
  • The unit of measurement matches the dataset's unit.

The dataset extent supports recalculation and copy-paste operations, as explained below:

  • Recalculate: The dataset extent can be recalculated based on the spatial objects within the dataset. For details, see Recalculate Mosaic Dataset Extent.
  • Copy-paste: Click the Copy button to copy the current dataset extent. You can also click the Paste button to set the copied left, lower, right, and upper values to the current extent.

Dataset Description: Displays the description of the vector dataset, which can be edited here.

Coordinate system

Coordinate system toolbar button functions:

  • Reset Coordinate System: Click this button to select a coordinate system from the dropdown list or open the coordinate system settings dialog for further configuration. For details, see Projection Settings Window.
  • Copy Coordinate System: Click this button to open the Copy Coordinate System dialog. You can copy coordinate system information as the projection information for the current dataset. There are two ways to copy the coordinate system:
    • Copy the coordinate projection information from an existing datasource in the current workspace.
    • Copy the coordinate projection information from an existing dataset in the current workspace.
  • Export Coordinate System: Export the dataset projection information as an XML file (*.xml).
  • Import Coordinate System: Import a projection information file (*.xml) as the dataset projection.
  • Projection Transformation: Click this button to open the Projection Transformation dialog, where you can select and import a projection information file. Supported formats include:
    • Shapefile projection files (*.shp;*.prj)
    • MapInfo interchange format (*.mif)
    • MapInfo TAB files (*.tab)
    • Raster projection files (*.tif;*.img;*.sit)
    • Projection information files (*.xml)

For details on projection transformations, see Projection Transformation Dialog Operations.

Mosaic

Clicking the Mosaic option in the properties panel will display the basic information and no-value settings for the mosaic dataset.

The basic information includes:

  • The number of bands in the mosaic dataset image
  • The pixel format of the stored image
  • The width and height of the mosaic dataset

The no-value information can be modified in the following ways. For details on how to use mosaic dataset no-values, see Mosaic Dataset No-Value Description:

  • Unified Setting: Select all or specific bands from the no-value list, then click the Unified Setting button to apply a uniform no-value setting to the selected bands.
  • Recalculate: Click the Recalculate button to compute the no-value of the first image as the mosaic dataset’s no-value.
  • Manual Modification: If different bands have different no-values, you can manually edit the no-value for each band in the table.

After setting the mosaic dataset no-value, images without no-value information will not automatically use the dataset’s no-value as their own. You can configure the no-value settings as follows:

  • Replace Missing Image No-Value: This option is unchecked by default. If checked, images without no-value information will use the mosaic dataset’s no-value, while images with no-value information will retain their own values.
  • Replace All Image No-Values: This option becomes available only after checking Replace Missing Image No-Value. If selected, all images, including those with no-value information, will be forced to use the mosaic dataset’s no value.
Caution:
  • If the modified no-value has already been applied, clicking the Reset button will not revert it to the previously applied value.
  • After enabling Replace Missing Image No-Value and Replace All Image No-Values, click the Apply button for the changes to take effect.
